In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the letter A may generally designate the improved combined radio, phonograph, and picture projector, which may include a casing B having anamplifying horn G mounted therein in a cooperative ,relation for receiving sound from radio apparatus D and phonograph apparatus E, and for also receiving through the passageway or channel thereof projected rays of light from moving picture apparatus F in a projected relation upon a screen G supported by the said horn C,

Referring to the means B the same referably includes a bottom 10; right and left side walls 11 and 12; a rear wall 13; and a top wall 14, defining a horizontally elongated compartment 15, normally open at the front thereof, and having preferably hinged doors or closures 18 and 19 respectively vertically hin ed on the front edges of the walls 11 and 12 or swinging to a closed or open relation with respect to the compartment 15, as illustrated in the drawings. The top wall 14 is preferably provided with an opening 15' therein, which opens into a compartment 16 wherein a phonograph turn table 17 is 1'0? tatablysupported on a horizontal partition 18. The artition 18 at its sides may besecured to t e side walls-11 and 12, and at its front and rear ends terminating short of the rear wall and front doors; a front partition 'wall 20 being provided therefor'and a rear partition wall 22, thus defining the shallow compartment 16 in which the phonograph turntable 17 is rotatably mounted for suporting a record in the conventional relation: he tone arm E is pivoted at 25 on the partition 18, and-it may also be used forsupporting a motor 27 on its bottom surface, in the compartment 15.

The amplifying horn G is preferably of trumpet-shape formation. supported longitudinally in the compartment 15, and flaring from the front end in a diverging relation to the rear end thereof. The front end of the horn Ois open, and faces the frontopening of the casin B, and over which the screen G may be etachably supported, as illus- 35 54 is of course mounted in the compartment between the same and the bottom 10. The

partition wall extends from the opening at the front of the compartment 15 to about the middle of thecompartment 15, and there a rear wall 41 terminates the record compartment 42, which may have an auxiliary supporting shelf 43 therein, if desired. In order to support the front ends of the partition wall 40 and shelf 43, a front wall or support 44 may be provided, set into the casing compartment 15 so that the doors 18 and 19 may properly close the compartment 15, as illustrated in Figures 1 and 3 of the drawings. The horn C at its front end rests upon this wall or support 44, and the said horn extends rearwardlyabove the partition 40, and at its rear end is provided with a downturned flaring neck or inlet 50, providing a small channel passageway 51 which communicates with the main channel or passageway 52 of the horn C, and which inlet or neck 50 is adapted to be connected at its lower end to themouth of a'radio loud speaking unit 54,

' of a radio apparatus D, as is well illustrated in Figure 1 of the drawings. This radio unit 15 rearwardly of the wall 41.

The amplifyin horn C is also provided with a relatively arger inlet neck 57, arcuating upwardly in a Y-shaped relation with respect to the inlet or arm 50; said inlet or arm 57 having a channel 58 therethrough, and said inlet 57 at its reduced end being suitably connected in the phonograph motor board or wall 18, in communication with the tone arm E, so that the latter may swing over the record in conventional relation and transmit the sound reproduced into the channels 58 and 52, as can readily be understood from Figure 1 of the drawings.

Inthe rear half of the left wall 21 of the casing B is provided an opening 60, in which a door or closure 61 is hingedly connected at 62 adjacent the left edge of the rear wall 13. The said door 61 is provided along the lower margin thereof with a horizontal table 63, preferably in the shape of a 90 segment, which swings into the compartment 15 immediately over the bottom 10 of the casing B, and which supports thereon themoving picture projecting machine F. The machine F is upwardly t1lted at its front end, and may rest on an auxiliary rearwardly and downwardly sloping platform provided on the platform or table 63, as illustrated in Figure 1, so that the telescope or lens piece 73 of themoving picturemachine F will cast of light from the motion picture machine F i canbe cast directly on the screen G along the channel or passagewayv 52 of the horn O, as

will be apparent from Figure 1 of the drawings. J

The motion picture machine F of course supports reels 83, and the machine F may be swung by opening and closing of the door 61, 'to the outside of the compartment 15, to facilitate changing of the reels, in a relation which is apparent from Figure 3 of the drawings.

When the door 61 is fully closed the motion picture machine F is in position to project its rays thru the port 80,'as illustrated in Figure 1. I

In order to accommodate a number of reels offilm, it is preferred to provide partitions in the compartment 15 along the right hand wall 11 at the rear thereof, to define a compartment 90, having an opening in the side wall ll thereto over which the closures or doors 91 operate; the compartment 90 being adapted to receive reels 93 therein for the motion picture projecting machine F; the compartment 90 in horizontal depth being limited so as not to interfere with the machine F, as will be apparent from Figure 8 of the drawings:

As to the radio apparatus, the loud speaking unit 54 is a ortion thereof, and the dial panel 100 is pre erably supported at the upper rear corner'of the casing B; the rear portion of the top wall 14 and upper portion of the rear' wall 13 being cut away to diagonally'accommodate the panel 100; A closure 102 may be hingedly connected at 101 on the upper end of the wall 13, which swings to a closed diagonally inclined position to cover the panel 100, as will be apparent from Figure 1015 the drawings. Of course on the rear of the panel 100 may be provided any suitable mechanism, such as condensers 102 and the like, suitably connected by wires (not shown) to the loud speaker unit 54. As a part of the radio apparatus there may also be provided a battery compartment 105, the

same being in fact an extension of the phonograph turn table compartment 16, but separated therefrom by the wall 22 above mentioned. The bottom '18 which forms the support for the turn table of the phonograph is extended rearwardly and at its rear end is provided with a vertical wall 107 spaced with the wall 22 to provide the compartment 105 extending from side to side of the casing B, which receives the A and batpanel 100 will inten Iteferring to the screen G, the same may be o-ffrosted' glass, silk, or other fabric, it bein necessary that thesame be translucent. Preferably the same includes a screen body readiliy .120, which may be of any suitable material ,as above mentioned, which is peripherally enclosed in a metal frame 121 of rectangular formation. The front end of the ,horn C has an o 'ening which conforms to this rectangular drmation of the screen G, and the screen G is adapted to fitover the front opening of the horn O, in the relation illustrated in the drawings. In order to most efiiciently position the screen G for picture observation, the same is inclined at an acute angle to a vertical plane; the front margins of the horn C terminating in a plane at an angle acute to thefvertical, so that the screen G may rest thereaga-inst in a plane acute to the vertical, I upwardly inclining into' the compartment screen G against slipping from the lower edge thereof which rests upon the front wall or supporting block 44 above described; the'said block 44 having corner lips 123 thereon which secure the from its restin position against the open end of the horn It is to be .noted that this inclined positioning of the screen G will enable people in the room to more efiiciently see ictures reflected on the screen body 120, and indeed one of the 1n the room,

of the picture on the screen G, free of interillustrated in Figure important advantages secured by inclining the screen is that the same is overlappedb the front end of the top wall 14 of the casing, which shades the same from any lights and enables a better observation ference by illuminant within the room in which the machine may be operating. It is to be particularly noted that the screen G only rests at its lower portion on the block 44, and entirely within the compartment 15, so that the doors 18 -andl19 can be closed. The block or front wall 44, as is more clearly 6 is rece'med at 130, into which an operator may slip his pr her fingers beneath a substantially J-shaped -handle 131 which is secured on the screen G and extends into the recess 130; this handle 131 being gripped by the hand of the operator for the purpose of slightly elevating the screen G until it is free of the retaining lips 123 so that the screen G may be entirely detached vfrom the casing wall of the horn without departing from the spirit of B, or so that the upper end thereof may be slipped into-the compartment 15 above the. horn G into 'a resting relation upon the top wall of the horn G; the screen coming to rest" at its normal to against a stop block 135 secured on t e top 0, in order to position the handle 131 of the screen G where it may be easily grasped when it is desired to take the screen G from its inoperative collapsed position in Figure 7, to the operative position in Figures 5 or 6.

. suitable crank 140 may be provided for the motor 27, which is preferably of the spring wound type. A top lid or closure 142 may be provided for the compartment 16, collapsed into the same plane as the top wall of the casing B, as'illustrated in Figure 1. In order that the motion picture machine may beconveniently operated, the switch de.--

tails 146 thereof may be mounted on the closure 61,v as may also the rheostat- 147Las'i1: lustrated in Figures 8 and 90f the drawings.

From the foregoing description of thisim vention it is apparent that a novel type of combined radio, phonograph, and motion pic.-

edge

ture projector has been provided, which are compactly arranged in a cooperative .assem blage of details which will permit of rela tively small rooms receiving these three enter? taining devices in a single unit; This renders a device of this character. practical for home use, although the application of such details thereof may be made to devices adapted for other uses, such as advertising. I
